BEDSPRING.

The object of my invention is to provide a support for the coil or helical springs of the bed which will yield under pressure thereon and increase the resiliency of the bed.

A further object is to provide means for supporting the coiled springs against lateral or sidewise pressure which would tend to tip and distort the springs; the general effect of my improvement being to provide a bed that will retain its original form and yielding characteristics even after continued use.

Other objects of the invention will appear from the following description and the accompanying drawings and will be pointed out in the annexed claims.

In the accompanying drawings forming part of this specification,

Figure 1 is a plan view of a bed spring embodying my invention;

Figure 2 is an enlargedxdetail view of a portion of the bed;

Figure 3 is a sectional view on the line 83 of Figure 2;

Figure 4 is a sectional view on the line 44 of Figure 2;

Figure 5 is a detail sectional view of a portion of one side of the bed.

In the drawing, 2 represents the side rails, preferably of suitable tubing and 3 the end rails secured by suitable means to the side rails and composed preferably of angle bars. Between the end rails 3, a wire cable 4 is strung back and forth, with the stretches in parallel relation, and connected at the ends of the loops to suitable pins- 5 mounted in the end rails. This cable is referably composed of twisted wires and is a apted to yield under a load and thereby increase the yielding and resilient characteristics of the bed.

For holding the parallel stretches of the cable together, I provide tie-bars between them; 6 representing .a series of short bars connecting adjacent stretches of the cable and holding them in parallel relation. There may be any desired number of these bars placed at suitable intervals between the stretches of the cable. 7 representssimilar bars having their ends twisted around cables which are somewhat remote from each other and bridging intermediate cables and the ends of these bars are also preferably twisted around the lower coils of the helical springs 8 seated upon the cables and held thereon by their connection with the bars 7 The lower coil of the springs is preferably of sulficient diameter to extend over four adjacent stretches of the cables as I have found that a convenient number in the manufacture of the bed; thesefour cables forming a substantial seat and support for the springs and the bars 7 serve normally as a means for connecting the outer cables of each group together by rigidly securing the lower portion of the spring coils to the cables, preventing any pos sibility of the springs being displaced in the bed. As shown in Figure 3, the connecting bars 7 are differently arranged; some of them extending along the under side of the cables and someof them on the upper side and in each instance serving as a means for securely tying the cables and the springs together.

A considerable space is provided between the side rails 2 and the adjacent stretch of cable and to support the springs over this space, I prefer to have arms 9 preferably integral with the side rails and projecting inwardly in a horizontal direction therefrom, there being one arm forming a support for each'coiled spring above. The arms have holes 10 therein through which the lower coil of the spring is inserted and secured.

The upper portion of the bed comprises end rods 11 and side rods 12. The upper coils of the springs adjacent the side and end rods are anchored thereto by means of wires 13 which are twisted around the upper coils of the springs and at intervals have loops 14 formed therein to overhang and restupon the rods Hand 12, thereby holding the springs in an'upright position and in the desired relation to theupper and lower rails and rods of the bed. Between the end rods 11 at the top ofthe bed, a series of cables 15 are stretched having their ends provided with guards 16 mounted on the rods 11; the cables being preferably stretched in pairs between the longitudinal rows of springs 8 and each cable being inserted through the upper loops of the adjacent springs and through the end coils of a series of coiled tension springs 17, having their ends coiled about the upper loops of the springs 8, thereby tying the ad j acent springs together and holding them all in an upright position and insuring simultaneous lateral or sidewise strain thereon. In other words, a downward pressure on one spring or roup of springs will be transmitted through the cables 15 and tension springs 17 to the other springs so that all of them will move in unison as one piece. The springs 17 provide a lateral connect-ion between adjacent springs, operating to yieldingly hold such springs together and cooperating with and supplementing the function of the'cables.

As an additional means for holding the upper portion of the bedagainst lateral sway or motion, I provide anchoring rods 18 having their ends provided with hooks 19 to engage the side rods 12 and their inner portions provided with loops 20 which are bent outwardly andseated on the group of cables adjacent the side rods with the end portions 21 of the loopsrbent downwardly around the outer cable of the group, as shown clearly in Figure 5. These anchors serve to hold the upper portion of the bed against lateral or sidewise lurch; cooperating with the other tying members to support the springs in their upright working position.

I do notin this application confine myself to the particular structure shown such as the arrangement of the cables 15 at the top of the bed, as these cables may be omitted and another structure employed in place of them without affecting the utility of the cables 4 as a supporting means for the helical springs.

I claim as my invention:

1. In a bed spring, lower side and end rails, and cables connecting the end rails, upper. side and end rods, a series of helical springs seated upon the cables, and U-shaped anchoring rods, each having hooked upper ends engaging an upper side rod and extending inwardly and downwardly therefrom, and having its inner portion reversely bent outwardly towards the lower side rod, and seated across the members of a group of cables, and terminating'in a hook-like portion which is shouldered around the outer cable of the group and whereby the'upper portion of the bed is held against lateral or sidewise lurch.

2. A bed spring comprising a bottom frame and a wire cable strung back and forth on said frame with the stretches in parallel relation, helical springs seated upon and attached to said cable stretches, tie bars for securing the cables in spaced relation, some of said bars having their ends twisted around the cables and around the lower whorls of the springs, and bridgin the lower whorls or loops in diametrica relation, horizontal laterally arranged tension springs connecting with the top loops of the helical springs,

and cables parallel with the lower cables extending between longitudinal rows of springs each cable being inserted through the upper loops of the adjacent springs and through the end coils of the lateral tension springs.

3. A bed spring comprising a bottom frame and a wire cable strung back and forth on said frame with the stretches in parallel relation,helical springs seated upon and attached to said cable stretches, tie bars for securing the cables in spaced'relation, some of said bars having their ends twisted around the cables and around the lower whorls of the springs, and bridging the lower whorls or loops, said bars being placed transversely with relation to the cables, the lower end of the coil springs resting upon four of the cables, and the bars extending across four cables, the marginal rows of springs at the sides being supported by arms rigidly connected with side bars of the frame, an upper frame and cables carried thereon, horizontal laterally arranged tension springs connecting with the top whorls or loops of the vertical springs, and cables stretched in pairs between longitudinal rows of springs each cable being insertedthrough the upper loops of the adjacent springs and through the end coils of the lateral tension springs, thereby tying the adjacent springs together and holding them in an upright position 4. A device of the class describedcomprising upper and lower frames, wire cables arranged on both frames in aseries of parallel stretches lengthwise thereof, springs having coils seated upon and secured to groups of lower cables, springs transversely connecting upper coils, transversely of the frame, portions of the cables of the upper frame being looped through the upper coils and secured by the springs.

5. A device of the class described comprising upper and lower frames, wire cables arranged on both .frames in a series of'para'llel stretches lengthwise thereof, springs having coils seated upon and secured to groups of lower cables, springs transversely connecting upper coils in :d'iametric relation and transversely of the frame, portions of each cable of the upper frame being looped through an upper coil and secured to a corresponding spring, whereby the springs act to secure the loop portions in looped position.

6. A bed spring comprising upper and lower frames, a lower frame having a wire cable arranged in parallel stretches, springs seated upon groups of lower cables, and U- shaped anchoring rods having terminals secured to the side bars of the'nupper frame, and extending inwardly and downwardly therefrom, and having'an inner portion reversely bent outwardly and seated across groups of cables, and having a terminal portion secured to the outer cable of a group.

In witness whereof, I have'here'unto set my hand this 2d day of February 1924.
